Problem: When calling setpos() with a buffer argument it often is ignored.
(Matthew Malcomson)
Solution: Make the buffer argument work for all marks local to a buffer.
(neovim vim/vim#5713) Add more tests.

Fix quickfix performance optimization which prevented quickfix items
from being updated when there were multiple windows with location lists
but the buffer with errors only in one of the lists.
In order to re-order marks according to the :move command, do_move()
uses mark_adjust() in a non-standard manner. The non-standard action is
that it moves some marks *past* other marks. This doesn't matter for
marks, but mark_adjust() calls foldMarkAdjust() which simply changes
fold starts and lengths and doesn't have enough information to know that
other folds have to be checked and reordered.
The array of folds for each window are assumed to be in order of
increasing line number, and if this gets broken some folds can get
"lost".
There has been a previous patch to avoid this problem by deleting and
recalculating all folds in the window, but this comes at the cost of
closing all folds when executing :move, and doesn't cover the case of
manual folds.
This patch adds a new function foldMoveRange() specifically for the
:move command that handles reordering folds as well as simply moving
them. Additionally, we allow calling mark_adjust_nofold() that does the
same as mark_adjust() but doesn't affect any fold array.
Calling mark_adjust_nofold() should be done in the same manner as
calling mark_adjust(), but according changes to the fold arrays must be
done seperately by the calling function.

Also make setpos("'A", [999, 1, 1, 0]) fail, i.e. return -1 (assuming there is no buffer 999).
Fixes#5713
Background:
`:help setpos()` mentions an argument `"bufnum"` that determines the buffer a mark should be put in.
This argument is respected for uppercase marks, but not for lowercase marks.
This is reasonable (though I personally would like `setpos()` to be able to set marks in other buffers), but the help doesn't mention this anywhere.
It's also strange that attempting to change buffers with `setpos('.', [bufnr('#'), 1, 1, 0])` alerts the user that having a different buffer is an error, while attempting to set a mark with `setpos("'d", [bufnr('#'), 1, 1, 0])` doesn't tell the user that the `"bufnum"` argument is an error.
- Eliminate/isolate static/global variables
- Remove special-case parameter from buflist_new()
- Remove special-case ECMD_RESERVED_BUFNR
- To determine when u_undo_and_forget() should be done, check
b_changedtick instead of a heuristic.
- use mb_string2cells() instead of strlen() to measure the :sub patterns
- call ml_close() before buf_clear_file(). Avoids leaks caught by ASan.

Regarding the individual items in the header:
`Vim - Vi improved by Bram Moolenar`
Bram Moolenar is already mentioned throughout the documentation, as
well as the intro screen.
`:help uganda`
It's already shown to all users who don't use `shortmess+=I` upon
starting nvim, and is already placed prominently in help.txt, i.e.,
`:help` run with no arguments.
`:help credits`
Already mentioned near the top of help.txt.
`README.md`
Already mentioned in develop.txt.
For compatibility the following things are done:
1. Items with type greater then greatest type are ignored when reading and
copied when writing.
2. Registers with unknown name are ignored when reading and blindly copied when
writing.
3. Registers with unknown type are ignored when reading and merged as usual when
writing.
4. Local and global marks with unknown names are ignored when reading. When
writing global marks are blindly copied and local marks are also blindly
copied, but only if file they are attached to fits in the `'N` limit defined
in &shada. Unknown local mark’s timestamp is also taken into account when
calculating which files exactly should fit into this limit.
5. History items with unknown type are ignored when reading and blindly copied
when writing.
6. Unknown keys found in register, local marks, global marks, changes, jumps and
search pattern entries are read to additional_data Dictionary and dumped (of
course, unless any of these elements were not overwritten later). It
obviously works only for values conversible to Object type.
7. Additional elements found in replacement string and history entries are read
to additional_elements Array and dumped (same: only if they were not
overwritten later). Again this works only for elements conversible to Object
type.
8. Additional elements found in variable entries are simply ignored when
reading. When writing *new* variables they will be preserved during merging,
but that’s all. Variable values dumped from current NeoVim session never have
additional elements.
What works:
1. ShaDa file dumping: header, registers, jump list, history, search patterns,
substitute strings, variables.
2. ShaDa file reading: registers, global marks, variables.
Most was not tested.
TODO:
1. Merging.
2. Reading history, local marks, jump and buffer lists.
3. Documentation update.
4. Converting some data from &encoding.
5. Safer variant of dumping viminfo (dump to temporary file then rename).
6. Removing old viminfo code (currently masked with `#if 0` in a ShaDa file for
reference).
We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
